Slacktivism versus real engagement is a false dichotomy - the fact is that smart technologists who care about the world are innovating new ways for people to get involved in the causes they care about. Get used to it.

Now, however, as we enter the next phase of this trend, questions still circle around the relationship between the new, less tested forms of involvement and traditional forms of volunteering and service that are still the bedrock of thousands of social change organizations.

If new technologies are adding more rungs to a ladder of engagement in the form of sharing, viral promotions, micro-volunteering, and micro-giving, what's at the top and the bottom? Where do these actions live beside other innovative, non-technical forms of volunteering -- such as pro bono and skilled models? And what are the right business models for social enterprises that are innovating these technologies?

Join moderator Robert Rosenthal from the pioneering social enterprise VolunteerMatch (www.volunteermatch.org) as he discusses these issues with technologists from three bleeding edge social change Web services: Dan Jacobs, founder of Everywun (www.everywun.com), Jacob Colker, co-founder of The Extraordinaries (www.beextra.org), and George Weiner, CTO of DoSomething.org.
